VehicleJourney#in_purchase_window: Use table namespace in query

We were getting this errorwhen filtering by purchase window on the
`ReferentialVehicleJourneys#index` page.

An example of a filter query that triggered the error:

We're trying to match `VehicleJourney`s here, so qualify the `id` column
with the table name to fix the error.
